What motivates u to live no matter what?

Actually, I have asked this Q in chatroom but I decided to post here to get wider, more profound advice. My Q is straightforward.
What are those things in your life that motivates u to get up every day, go to work, eat, sleep, and live your life no matter how painful, miserable, unbearable, and suicidal you feel?
Is it family, self-pride, religion, afraid of afterlife, hope, etc...?
